This invention refers to a new and improved system for the constructionof walls with the corresponding foundations by the process of mould-'.ing.

An object of the invention is to obtain a maximum perfection, rapidityand economy in the construction of walls of cement or similar materialwithout metallic core, as well as their corresponding foundations, by aspecial system of moulding and with the aid of special implements and ofa special disposition of the structure of the moulds.

The characteristic details of the system, within the mechanical parts,are clearly set forth in the following specification and in theaccompanying drawing, which serves as an illustration of the system andin which the same parts in the several figures are indicated with thesame reference numbers.

Fig. 1 is a view showing a part of a foundation, already finished on theleft hand side, and with the moulds ready for making the casting on theright hand side.

Fig. 2 is a view of a special piece K which serves for the uprights Pwhich support the structure of the mould, and which serves also forfixing the Width of the mould or distance between the boards of thesame.

Fig. 3 is a view of a modified form of the same with bores T which maybe of any convenient form and without the tongues L shown in Fig. 2.

Fig. 4 shows the manner in which the piece shown in Fig. 2. and Fig. 3is placed on the foundation.

Fig. 5 represents the general disposition, in perspective view, of thecomplete moulding structure. In this figure is seen the hopper V for themortar or mixture. This hopper is separate and movable from theframework.

Fig. 6 is a front view of the special multiple and variable square whichis used for placing the boards C which form the casing of the mould forthe foundation and which are secured to said square by means of screws.

This square is provided with rectangular irons A which serve for givingform to the upper platform which will be the base D for supporting thewall construction which is going to be moulded. In this figure are alsoseen, in profile, the boards C nailed to said square.

Fig. 7 shows the form of the boards C.

Fig. 8 is a side view of the general disposition of the frameworkmounted on the foundation C, the uprights P, the boards M and the jointsK alternated in vertical and horizontal senses.

Once the framework has been mounted in the manner described, the mortaror mixture is poured in to make the wall construction. After thestructure is taken apart by removing all the boards and the uprightsleaving the joints K which will be embedded almost completely in themortar or mixture. The free and visible ends or parts of these jointsare thereafter out, which, is very easy as the joints are made of sheetmetal or other similar material.

As these joints can be made cheaply, the cost of the construction of theframework will not be higher and no nailing of the boards will benecessary, wherefore said boards may be used for any length of time.

In the construction according to the system of my invention, the base isfirst constructed by means of the variable squares shown in Fig. 6. Withthese squares it will be possible to mold the foundation with any kindof inclination. In order to make the platform D seen in Figs. 1 and 4,the angle irons are placed on the inside of the horizontal iron and thedistance between these angle irons will be the width of the platform onwhich the wall of the same width is going to be constructed. When theconcrete is poured into the mold of Fig. 6, it will first reach theupper edge of the boards fixed to the inner sides of the vertical armsof the square and will thereafter fill the space between the angle ironsand thus form the platform D.

The tie shown in Figs. 2 and 3 is very simple in construction as it ismade of one single strip of sheet metal bent and cut out to make theperforations for the uprights, the notches for the boards and the wings.These ties are intended to remain in the construction, and only theparts which project from the outside of the boards are cut off whentheconcrete has set in order to free the uprights. Thus the tie accordingto this invention is not one which is used over and over again in acontinued wall construction, but is used in any number required andremains, as said, a part of the construction. The angle irons A do notbecome embedded in the concrete as they are fixed to the horizontal ironand will be lifted up with the square when the concrete has set.However, they may also be attached to the said iron in such a mannerthat they can be separated from the square before this is lifted up,whereafter they may be taken out lengthwise.

Looking at-Fig. 1, the platform D is made by the said] angle irons andwill be of the width of the wall to be erected on said platform.

Having thus described the invention, what I claim is:

1. An apparatus for the construction of wall foundations of cement orsimilar material comprising a molding framework and mold wallsassociated with the framework, said framework comprising a plurality ofbracing elements, each of which consists of a pair of spaced uprightmembers, a connecting member adjustably attached intermediate its endsto the upper portion of each upright member, a strut pivotally attachedto each upright member adjacent the bottom thereof, the free end of oneof said struts being adjustably attached to one end of the connectingmember and the free end of the other strut being adjustably attached tothe other end of the connecting member, and spaced parallel angle ironscarried by the connecting member for forming a platform on the uppersurface of the foundation.

2. In a concrete wall mold form consisting of a pair of spaced sideWalls formed of a plurality of horizontal boards arranged in tiers withtheir side edges abutting, spacing and tie bars for bracing, spacing andconnecting opposite pairs of superadjacent boards of said mold form,said bar being formed of a flat piece of metal having flanges extendingsubstantially the full length thereof, one of said flanges being bent toextend in one direction from the flat piece of metal and the otherflange being bent to extend in the 0pposite direction from the flatpiece of metal, tongue-like portions struck out of each flange adjacentthe ends of the bar and being in the same plane as the flat piece ofmetal to provide notches in the flanges adapted to cooperate with theboards of the wall of the mold to maintain the same in properspaced-apart relation, tongues struck out of the flat piece of metalimmediately adjacent the notches formed in the flanges thereof toprovide an opening to receive aligning rods, said tongues being adaptedto cooperate with boards received in the notches of the flanges, and aplurality of verticalaligning rods extending through superposed tie barsfor aligning the side walls of the mold form.

3. A spacing and tie bar for bracing, spacing and connecting oppositepairs of superadjacent boards forming the walls of concrete wall moldforms, said bar being formed of a flat piece of metal having flangesextending substantially the full length thereof, one of said flangesbeing bent to extend in one direction from the flat piece of metal andthe other flange being bent to extend in the opposite direction from thefiat piece of metal, and tongue-like portions struck out of each flangeadjacent the ends of the bar and being in the same plane as the flatpiece of metal to provide notches in the flanges adapted to cooperatewith the boards of the Wall of the mold to maintain the same in properspaced-apart relation, the flat piece of metal being provided withopenings adjacent the ends thereof for the reception of verticalaligning rods, said bars being adapted to be placed horizontally in abuilt-up mold and adapted to cooperate with vertical aligning rodsextending through the openings adjacent the ends thereof for retainingmold boards in assembled relation in any desired height, said openingshaving the material struck out therefrom attached to the innermost sidesthereof so as to be in a position to engage mold 1U
